PHILIP E. BER, OF BEVERLY, MASSACHUSETTS.

IMPROVEMENT IN WELLS FCR WATER-MAIN TAPS.

Specicaton forming part of Letters Patent No. 129,246, dated July 16,1872.

The common mouths or gate-wells consistv usually of a pyramidal box openat bottom and top, and extended from the waterppe up to the sidewalk,each having to be made of a v depth to correspond with that of the pipebeneath the top ofthe roadway or sidewalk.

As the distributin g-pipes and mains of waterworks when laid generallyvary in their depths below the surface of the earth, they requiregatew'ells to correspond to suc-h depths Whenever such wells arerequired to be used.

In carrying out my invention I make the gate-well in two or more conicalor pyramidal sections or frustums, A B, arranged with their lesser basesupward, and with the upper part of the lower frustum disposed within thelower part of the upper, the same being so that while the lower frustummay rest on the water-pipe C and encompass'the gate-shank a, the upperfrustum may be raised or depressed on the lower arm to the desirablealtitude to bring the cap-ring b to the level of the sidewalk or roadwayD. After the two frustums may have thus been arranged cement is to beplaced in the space between them, and should extend down to the base ot'the lower `frustum and entirely around suchl frustum, the mass of cementshown at d having a tapering outer surface whose diameter is greatestat'its base, the whole being to prevent the earth, by the action offrost, from adhering to and lifting the well out of place.

A cover, E, is to be placed on the cap-ring and within the upperfrustum, and upon the top of the lower one there areto be laid twocovers or a cross-partition, G G, so as to form a deadair space orchamber, H, between the two covers G G and the cover E, the same beingto protect the pipe and its valve or gate from being frozen.

I claim- 1. The water-gate well or mouth, n1 de in two or morepyramide-l or conical sections or frustums, A B, and arranged togetherand with cement d, all as explained.

2. -Also the combination and arrangement of the caps or covers G and Hwith the two frustums A B, arranged andcombined with and by means ofcement d, all as explained and represented.
